System Status Management (SSM) is the science of being in the right place with the right resource at the right time to meet the patient’s need. Â Some say it is the practice ofÂ placing ambulances on street corners, but the crucial thing we must remember is that the patient is having the emergency so we must be poised to respond with minimal delay and maximum impact. SSM takes the intelligence products of demand analysis of both time and space and matches manpower and availability to deploy a responder as close to the patient as possible. Â This achieves a minimal response time for the patient and reduces time spent running under emergency conditions for the crew (and distracted pedestrians!).
